To (ZZZ whom it may concern:

Be it known that I, ELIAS A. STARE, a. citi zen of the United States, residing at Sibley, in the county of Ford and State of Illinois, have invented a new and useful Improvementiu Muchines for Cutting Drain-Tiles to form Elbows, Branches, 8:c., of which theiollowing is a specificntion, reference being had to the accompnnying drawings. I

My inventionrelutes to an improvement 111 machines for cutting drain-tiles in order to Ins-ire elbows therefor while in a green or incompleted stage of manufacture; and is con sists in the peculiar conscruction and combinstion of devices than will be more fully set forth hereinafter, and particularly pointed out in the claims.

In the drawings, Figure l. is a side elevation of my invention. Fig. 2 is a, vertical longitudinal sectionulview of the some. Fig. 3 is a vertical transverse sectional view.

A represents a vertical rectangular frame,

f, secured at the lower ends of the arms f and connecting the some and the transverse beam f which is secured to the armsF at a suitable distance above the base-board f, and is concuved or hollowed on its inner side. A transverse rod, G, passes through aligned openings 6, and connects the beams B, so as to support the swinging frame F, either in a vertical posilsion or at any suitable angle.

H represents a pair of rocking arms, which are secured to or are formed with the inner ends of aligned longitudinal rock-shafts I, which are iournalcd in the center of the top frame, 0. Theserock-shsfts I are provided with an opera-ting bail or handle, K, by means of which the arms H may be swung through half a circle. The rock-arms H are provided on their outer sides with a, series of notches, 71 end a, wire, L, connects the said rocknrms and is stretched tightly between them and has loops?! formed at each. end, which loops enl gage with the notches h, and thereby secures the wire to the rocking arms at any desired adj ustmentthereon.

1? represents a longitudinal shaft, which is journallcd in blocks ill, which are secured on tlhe'under sides of the top frame, G, at one end thereof, and in the center of the said frame. To the inner end of this'shalft N is secured an arm, 91, by means of a bolt, in, the said arm extending at right; angles to the shaft), and is provided with a series of openings, n, by means of which it may be adjusted on the shaft, so as to cause one end of the arm to describe a circle of any desired diameter when the shaft is rotated. To this end of the arm is secured a onttingblade, O, which projects in a line with the shaft and at right angles from the arm.

The operation of my invention is as follows: The tile to be cut, in order to form an elbow while in a green stage or before it is burned, and while yet in a, plastic condition, is placed tile resting on the bottom board, f, and one side thereof being supportcdby the beam f. The cutting-Xvi re L is then adjusted on the arms H, so as to describe a circle having the same diameter as the tile, and the rocking arms are then swung through half a circle by means of the bail or handle, causing the wire to pass through the tile and cut it at the desired angle.

In order to cut the hole in the main t-ile said tile is placed in the frame F, and the latter adjusted to the desired position, and the arm n of the shaft; N is adjusted so as to cause the blade to describe 2. circle of the same diameter as the hole to be cut; in the tile. The shaft N is then moved inwardly in its bearings, so as to cause the blade to come in contact; with the side of the tile, and the said shaft is then operated by means of a suitable crank provided at its outer end, thereby causing the cuttingblade to cuta hole in the side of the tile.

A machine for cutting tiles thus constructed is extremely cheap and simple, performs its work with great accuracy, and is not, likely to get out; of order.

Having thus described any invention, I ole-inn- 1. The combination, in e machine for cutting dralimtiles, of the frame A, having the beams E, provided with the series of openings in the swinging frame F, the lower end of the e, the swinging frame F to support the draintiles while being out, and the rod G, for passing through the openings e, to support the frame F at any desired position, substantially as described.

2. The combination, in a machine for cut ting drain-tiles, of the supporting-frame and the rotating shaft M, carrying the cutting-blade O, substantially as described.

3. The combination, in a machine foroutting drain-tiles, of the rotating shaft M, having the cutting-blade O, laterally adjustable with relation to the said shaft, whereby the said blade is adapted to out openings of different sizes in the sides of the drain-tiles, subtantially as described.

4. The combination, inia machine for ;cutting drain-tiles, of the swinging frame F, for

to the path described by the swinging frame F, for the purpose set forth, substantially as described.

In testimony that I claim the foregoing as i my own I have hereto affixed my signature in i presence of two witnesses.

ELIAS A. STARE.
